Application filed January 8, 1995.

T aZZ whom, it may concern:

Be it known that LALERED H. DE CAMP, a citizen of the United States, residing at Trenton J unction,in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Hoisting and Conveying Machines, of which the following is a specification.

My improvement relates to that class of hoisting and conveying apparatuses in which shiftable supports are provided for sustaining the fall-rope during the operation of theapparatus.

As is well known to those'conversant with the art, provision for the prevention of the" sagging of the fall-rope is absolutely essential and the object of my invention is to provide forsuch purpose simple supports of light construction and means for automatically and uniformly delivering and distributing said supports along the line of the way of the apparatus when and as they are required for use and collectingand storing them out of the path of the traveling carriage of the apparatus when they are not in use.

In the drawings forming a part of this specification, Figure 1 is a side View of a hoisting and conveying apparatus embodying my invention. Fig. 2 is a side elevation of a portion of such hoisting and conveying apparatus, showing the upper part of the end supportthereof nearest the power-station and apparatus for delivering and distributing the fallrope supports. Fig. 3 is a plan view of a portion of the apparatus shown in Fig. 2, taken on the line b b therein. Fig. 4 is a front elevation, on an enlarged scale, of one of my fallrope supports, showing its operative connection with one of the pivoted parts used for opening and holding the supports. Fig. 5 is a detailed view showing the connection of the fall-rope-support delivering and distributing Serial No. 534,237. on, model.)

apparatus attached to the terminal support of the conveying apparatus in a diiferent manner from that indicated in Fig. 2.

In the drawings, 1 2 are the terminal supports of a hoisting and conveying apparatus.

carried thence over a sheave 8 (see Fig. 1)

and thencedown to a drum. 9 at the power station, around which drum'it is wound several times and carried thence over the sheave 10 in the terminal support 1, and thence around a sheave 11 on the terminal support 2 and back tothe other end'of the carriage 7, to which it is attached.

7 is the hoisting-carriage, of the ordinary constructiomwhich is well'known to those conversant with the art, and 12 is the fallrope, which is wound on the drum 13 at the power-station and carried over a sheave 14 on the terminal support 1, (see Fig. 2,) similar to the sheave 10 and located. on the same shaft, and thence over a sheave 15, and thence over a sheave 16 on the traveling carriage 7,

and thence around afall-block 1'7, swinging below the carriage and back to and around the sheavels onthe carriage 7, and thence down to the fall-block 17, to which it is attached.

Suspended from the tram-cable 3 near the terminal support 1 is a framework consisting of four upright members 19 2O 21 22, 19 20 being shown in side elevation in Fig. 2 and all four of said members 19 2O 21 22 being shown in horizontal cross-section in Fig. 3.

braced by the diagonals 25 26 and the horizontal braces 27 28,and the whole framework is. connected to the terminal support 1 by two pivoted links, one of which, 29, is shown in Fig. 2. The lowerend of the upright mem swaying of the framework.

her 19 is held Within a forked guide 30, fastened upon the terminal support 1, which guide 30 is provided to prevent the lateral Outside of one end of this framework is a horizontal transverse frame 31, which is held in its position by the braces 32, 33, 32, and 33 attached at their other ends to the uprights 20 and 22. A similar horizontal transverse frame 34 is attache'd to the uprights 20 and 22.

35 is a shaft threaded in its middle portion and supported in boxes 36 3738, placed upon different members of the framework above described. The middle box 37 is internally threaded. This shaft 35 is longitudinally grooved upon its end which carries the beveled gear 39, slidingly fixed upon said shaft 35 by a feather 40, as shown in Fig. 5. The gear-wheel 39 has a hub 41, which turns within the box 36, said hub carrying within it the shaft 35. The box 36 is doubled (see Fig. 3)

to act also as a bearing for the axle of the sheave 8, upon which axle is rigidly fixed the beveled pinion 42, which meshes with the beveled gear 39.

The fall-rope supports 43, 44, 45, 46, 47, 4S, and 49 are swung upon small grooved rollers which travel upon the tram-cable 3 and are formed of two depending iron bars which are attached together by two rivets 50 and 51, as shown in Fig. 4. About midway of their length there is passed through them a pivot upon which is supported a grooved roller 52. At their lower ends these iron bars diverge from each other, as shown in Fig. 4, and just above their point of divergence is fixed a bolt 53, upon which is placed a stiff spiral spring 54, which is held in place by an adjustable nut 55, placed upon the end of the bolt. Upon the inside of the two iron bars forming each fall rope support are placed two wearingstrips 56 and 57, made of metal and removable at pleasure.

Supported by the horizontal transverse frames 31 and 34 is a round rod 58, on which are pivotally mounted the operating-pieces 43, 44, 45, 46, 47, 48, and 49. These opcrating-pieces are shown in plan view in Fig. 3 and one of them is shown in side elevation in Fig. 4,and they are counterweighted,as shown. On their ends projecting within the framework they have formed upon their respective upper faces wedge-shaped raised portions or projections 59, 60, 61, 62, 63, 64, and 65. Each of these operating-pieces is provided at its end with a tongue 70, which tongues project toward the threaded portion of the shaft 35. These tongues 70 play into slots formed in a longitudinal bar or plate 71, supported by the horizontal transverse frames 31 and 34 and shown in side elevation in Fig. 6 and in plan view in Fig. 3 and in vertical cross-section in Fig. 4. This slotted bar 71 holds the tongues 70 in line when in their normal position, preventing their rising beyond their desired position, and also prevents lateral play of the operating-pieces. On the shaft 35 is rigidly The operation-of my device is as follows: d

When the conveying apparatus is about to be started up, the receptacle used for transporting loads is suspended close under the traveling carriage, which is located on the tramcable near the terminal support 1, and the fall-rope supports are in the position shown in Fig. 2. The drum 9, on which the running-line 6 is wound, is put in motion to draw the carriage out upon the line of the tramway, and the drum 13 is turned at the same speed to unwind the fall-rope. The motion of the running-line 6 is imparted to the sheave 8, over which it passes, and the beveled pinion 42, rigidly fixed to the axle of the sheave 8, is turned with the sheave and imparts its motion to the beveled gear 39, slidingly fixed upon the shaft 35, which imparts its motion to said shaft. Said shaft, being threaded to screw in the box 37, gradually moves in toward the terminal support 1, sliding within the gear 39, and as it moves forward the disk 72, which is rigidly fixed to the shaft 35, moves with it until the finger 73 on the disk 72 is brought in contact with the tongue 70 on the operating-piece 49 and depresses said operating-piece until the wed ge-shaped projection on the face thereof is drawn down from between the diverging ends of the fall-rope support 49. The withdrawal of this wedgeshaped piece 65 brings into action the spiral spring 54 on said fall-rope support 49, which spring drives together as far as possible the two iron bars composing the frame of said fall-rope support 49 and brings the pieces 56 and 57 into frictional contact with the running-line 6. The friction of these pieces upon the fall-rope is so strong as to cause the running-line to drag the support 49 with it in its progress, the small grooved roller at the top of the fall-rope support running upon the tram-cable 3. As the operation of the mechanism is continued the disk 72 continues to travel toward the terminal support 1 with the shaft 35, upon which it is fixed, and the finger 73 next comes in contact with the tongue of the operating-piece 48, which in turn is depressed and frees the fall-rope support 48, which is forced into frictional contact with the running-line 6 and carried with it in its course, as is the support 49. This operation is continued until the motion of the drum 9 ceases upon the arrival of the traveling carriage at its destination. The revolution of the drum 13 is continued to let out the fall-rope, and the receptacle is dropped in the usual manner to the ground to be loaded, the various fall-rope supports being spaced along the line of the tramway, as indicated in Fig. 1, and sustaining on their respective rollers 52 the weight of the fall-rope sufficiently to permit the loweringof the receptacle without difficulty. When the receptacle is loaded, reverse motion is given to the drum 13 and the receptacle is raised to the desired height beneath the traveling carriage, and the drum 9 is then set in reverse motion to wind the running-line 6, and the revolution of both drums is continued in the usual manner until the carriage is drawn in to the point of discharge. As the carriage progresses toward the support 1 the several fallrope supports are drawn into their stations,

within the framework shown in Fig. 2. If allthe fall-rope supports have been drawn out and spaced upon the line of the trainway, the first to arrive at its station is the their counterweights immediately the pressure of the finger 73 has beenremoved from their respective tongues) whenit reaches the wedge-shaped projection 59 on the operatingpiece 43 and is wedged thereon, thus separating the two bars of its frame sufficiently to take the frictionpieces 56 and 57 out of contact with the running-line 6, which proceeds on its way, leaving the fall-rope sup port 4-3 in the positionindicated in Fig. 2. The next fall-rope support 44 when brought in lodges in the same way upon the wedgeshaped projection 60 of its operating-piece, and so on. All the fall-rope supports lodge upon their respective wedge-shaped projections and are left in their respective stations, as shown in Fig. 2. It will be readily understood that when the motion of the drums 9 and 13 is reversed to draw the traveling carriage in to the point of discharge the reverse 7 movement of the running-line causes a reverse revolution of the sheave Sand through the gear connected therewith a reverse revolutionof the shaft 35 and disk 72. As this disk 72 travels back past the tongues of the operating-pieces the finger 73 comes in contact with these tongues on their under sides, and as the operating-pieces are held in their horizontal positions by their counterwhich,19, appears inFig. 7.

In Fig. 7 I have shown a modified form of attaching my fall-rope-support discharging and distributing apparatus to the terminal support of the tramway. In this figure I have shown the terminal support 1 with the tram{ cable 3 pivotally attached to it upon a bolt 80, to which said boltare suspended the uprights shown as19 and 21 in Fig. 3, one of over which passes the runningline 6, and the sheaves 10 and 14: over which pass, re spectively, the running-line 6 and the fallrope 12,swing within the standard I.
